DistilSenti-Net42M: Context Distilled Small Language Model For Sentiment Analysis

Model Architecture

Embedding Layer: Converts input text into dense vectors.
CNN Layers: Extracts features from text sequences.
Vanilla RNN, LSTM: Capture temporal dependencies in text.
Dense Layers: Classify text into sentiment categories.

Usage

You can use this model for sentiment analysis on text data. Here's a sample code to load and use the model:

python

from huggingface_hub import from_pretrained_keras
import re
import numpy as np
from tensorflow.keras.preprocessing.sequence import pad_sequences

# Load model
model = from_pretrained_keras("Ravinthiran/DistilSenti-Net42M")

# Example prediction function
def predict_sentiment(text, model, tokenizer, label_encoder):
    text = text.lower()
    text = re.sub(r'[^\w\s]', '', text)
    sequence = tokenizer.texts_to_sequences([text])
    padded_sequence = pad_sequences(sequence, maxlen=100)
    pred = model.predict(padded_sequence)
    sentiment = label_encoder.inverse_transform(pred.argmax(axis=1))
    sentiment_score = pred[0]
    return sentiment[0], sentiment_score

# Example usage
new_text = "I recently started a new fitness program at a local wellness center, and it has been an incredibly positive experience."
predicted_sentiment, sentiment_score = predict_sentiment(new_text, model, tokenizer, label_encoder)

print(f"Predicted Sentiment: {predicted_sentiment}")
print(f"Sentiment Scores: {sentiment_score}")

# Sample data

# Encode labels
label_encoder = LabelEncoder()

    sentiment = label_encoder.inverse_transform(pred.argmax(axis=1))
    sentiment_score = pred[0]
    
    return sentiment[0], sentiment_score

# Example usage
new_text = "I recently started a new fitness program at a local wellness center, and it has been an incredibly positive experience. The trainers are highly knowledgeable and provide personalized guidance to help me achieve my fitness goals. The facilities are state-of-the-art, with a wide range of equipment and classes to choose from. The supportive community and motivating environment have made working out enjoyable and rewarding. I have already noticed significant improvements in my health and fitness levels, and the positive changes have greatly enhanced my overall well-being."

predicted_sentiment, sentiment_score = predict_sentiment(new_text, tokenizer, model_hybrid)

print(f"The sentiment of the input text is: {predicted_sentiment} with scores {sentiment_score}")
